The late Malcolm Berko wrote a syndicated newspaper column where people wrote and asked for financial and investing advice.If it decriminalizes, you will see Big Tobacco buy everything. Altria (MO) is foaming at the mouth for this to happen.
Some years ago when a couple of states had legalized marijuana, somebody asked him for specific, publicly traded companies that would be good to own stock in (so as to cash in on all the money heading into the pot business).
As I remember Mr. Berko replied in his column that any specific company he suggested would be pure speculation at that point.
Berko said he had asked some folks in D.C. and NYC for their opinions on the long term prospects of investing in marijuana and he was told that when the dust finally settles, either Big Pharma or Big Tobacco will control the pot industry in this country.
I tend to agree. I think the Big Businesses will buy off the federal and state legislators and will get the laws tailored to pretty much exactly what they want.
